Sealed electrical connector

Abstract

An electrical connector comprises at least one chamber for accommodating at least one electrical contact and a seal arranged in the inlet region of the chamber through which the electrical contact is plugged through or pierced through when fitting the connector. Immediately behind and/or immediately in front of the seal viewed in the contact plug-in direction an admission region widened transversely to the contact plug-in direction is provided in each case for the sealing material displaced when the contact is plugged through or pulled out.

1. Electrical connector comprising at least one chamber for accommodating at least one electrical contact and a seal arranged in the inlet region of the chamber; said seal configured to permit the electrical contact to be plugged through or pierced through when the chamber accommodates the connector, wherein, immediately behind and/or immediately in from of the seal viewed in the contact plug-in direction, the chamber comprises an admission region that is widened transversely to the contact plug-in direction so as to accommodate sealing material displaced when the contact is plugged through or pulled out of the inlet region of the chamber. 
   
   
     2. Connector according to  claim 1 , wherein the cross-section of each admission region increases in the direction towards the seal. 
   
   
     3. Connector according to  claim 1 , wherein the rear admission region viewed in the contact plug-in direction is arranged between the seal and the chamber. 
   
   
     4. Connector according to  claim 1 , wherein the rear admission region comprises a juncture. 
   
   
     5. Connector according to  claim 1 , wherein the front admission region comprises a juncture. 
   
   
     6. Connector according to  claim 1 , wherein the rear admission region is designed to be of such a size that on fitting the connector at least substantially no sealing material comes into the chamber. 
   
   
     7. Connector according to  claim 1 , wherein the front admission region is arranged on the inside of a front wall of the connector provided with at least one Contact opening. 
   
   
     8. Connector according to  claim 7 , wherein the front wall is formed by an integral hinge flap. 
   
   
     9. Connector according to  claim 1 , wherein the rear admission region is bounded by at least two opposing walls diverging in a direction towards the seal. 
   
   
     10. Connector according to  claim 1 , wherein the front admission region is bounded by at least two opposing walls diverging in a direction towards the seal. 
   
   
     11. Connector according to  claim 1 , wherein the seal comprises a block seal. 
   
   
     12. Connector according to  claim 1 , wherein, viewed in the contact plug-in direction, the seal is divided into at least two layers. 
   
   
     13. Connector according to  claim 1 , wherein, in the region of each electrical contact, the seal, viewed in the contact plug-in direction, is divided into at least two plug-in regions spaced apart from one another at a distance in the contact plug-in direction. 
   
   
     14. Connector according to  claim 13 , wherein the seal, as a whole, is divided into at least two courses or layers, and the plug-in regions spaced apart from one another at a distance in the contact plug-in direction are distributed over these courses or layers. 
   
   
     15. Connector according to  claim 1 , wherein each plug-in region for the associated electrical contact is provided with an opening whose maximum diameter is preferably smaller than the maximum transverse measurement of the contact in question and in particular is smaller than the outer diameter of the lead in question on which the contact is provided.
